A 49 kg rock climber is climbing a 'chimney' between two rock slabs as shown below. Thestatic coefficient of friction between her shoes and the rock is 1.2; between her back andthe rock is 0.80. She has reduced her push against the rock until her back and her shoesare on the verge of slipping.a. Make a force diagram for the forces on her. Include the correct symbols for the type ofb. Write out the equations for Newton's 2nd Law that are pertinent to the problem: ΣFx =force and subscripts for the object the force is on and where the force is from.ma, &/or ΣFy = may.
